Abstract
Un método para producir gas natural licuado CARACTERIZADO PORQUE comprende: (A) comprimir una primera porción de un gas natural de alta presión, llevándolo a una temperatura por encima de su punto de congelamiento y turboexpandir dicha primera porción para producir al menos una parte de la refrigeración que se requiere para licuar la segunda porción remanente del gas natural; (B) licuar la segunda porción remanente del gas natural y subenfriar la mencionada segunda porción y evaporar rápidamente el gas natural subenfriado para producir vapor de evaporación rápida y gas natural licuado a baja presión; (C) comprimir el gas de refrigeración y turboexpandir el gas de refrigeración comprimido para producir el gas de refrigeración enfriado; y (D) calentar el vapor de evaporación rápida y el gas de refrigeración enfriado por intercambio de calor indirecto con el gas natural de alta presión para producir gas natural licuado subenfriado. El método de la reivindicación 1 CARACTERIZADO PORQUE la primera porción comprimida del gas natural se enfría para llevarlo a una temperatura por encima de su punto de condensación. El método de la reivindicación 1 CARACTERIZADO PORQUE la primera porción comprimida se enfría y se expande en una primera expansión para producir al menos una parte de la refrigeración requerida para licuar la segunda porción remanente del gas natural, y calentar dicha primera porción para llevarla a una temperatura por encima de su punto de condensación. El método de la reivindicación 1 CARACTERIZADO PORQUE el gas natural de alta presión se purifica en un primer sistema de purificación.
